From an environmental perspective, these lesser known creatures of coral reefs are important grazers that keep algae growth in check. During low tides, you can see them on the reefs at Toco, and you immediately know not to step on them. However, they are necessary for corals to have more space to grow. Recent studies have shown that human waste is linked to coral disease. If human activities continue to directly effect our aquatic creatures, we will lose our natural environmental resources. Nature awareness is the first phase of environmental stewardship, so when relaxing on the beach, feel free to walk through the water and count these spiny creatures, and know that they are as important as the fishes we catch and eat during lent.
